Doctrine DQL subqueries give a zero result - php

Question

I have three related entities : Group, GroupDefault, GroupDefaultTranslation on a Mysql server.
The Group entity stores the groups of a user.
The GroupDefault entity define the default groups for any user.
The GroupDefaultTranslation entity stores the translation for the default groups.
The relationships between the entities are types:
- ManyToOne between Group and GroupDefault
- OneToManu ent GroupsDefault and GroupDefaultTranslation
My goal is to display the list of groups of a user with the corresponding translation in his language parameter.
Here is my QueryBuilder with DQL query generated :
public function findByOwnerWithLanguage($languageCode, $ownerId)
{
$qb = $this->createQueryBuilder('g')
->select('g.name')
->addSelect('gdt.content AS name')
->join('g.parent', 'gd')
->join('gd.translations', 'gdt')
->where('g.owner = :owner');
//création de l'expression AND
$orModule = $qb->expr()->andX();
$orModule->add($qb->expr()->eq('g.parent', '0'));
$orModule->add($qb->expr()->eq('gdt.locale', ':language'));
$orModule->add($qb->expr()->eq('g.owner', ':owner'));
//Ajout de l'expression à la requête
$qb->orWhere($orModule)
->setParameter('language', $languageCode, \PDO::PARAM_STR)
->setParameter('owner', $ownerId)
->orderBy('g.isMyLightbox', 'DESC')
->getQuery()
->getResult();
return $qb;
// DQL Query :
// SELECT g.name, gdt.content AS name
// FROM Horyou\Bundle\CoreBundle\Entity\Group g
// INNER JOIN g.parent gd
// INNER JOIN gd.translations gdt
// WHERE g.owner = :owner
// OR (g.parent = 0 AND gdt.locale = :language AND g.owner = :owner)
// ORDER BY g.isMyLightbox DESC
}
And here is the output of the object var_dump :
object(stdClass)[1368]
public '__CLASS__' => string 'Doctrine\ORM\QueryBuilder' (length=25)
public '_em' =>
object(stdClass)[1362]

public '_maxResults' => null
public 'joinRootAliases' =>

'gd' => string 'g' (length=1)
'gdt' => string 'g' (length=1)
My problem is that the result is zero.
Does anyone see what is the error in my QueryBuilder?

Answer 1

Actually it's not a result - it's just a dump of a query builder object. I think you have to do something like this:
...
$qb->orWhere($orModule)
->setParameter('language', $languageCode, \PDO::PARAM_STR)
->setParameter('owner', $ownerId)
->orderBy('g.isMyLightbox', 'DESC');
$result = $qb->getQuery()->getResult();
return $result;
